Hey Jason thanks for the picture! The correct grease seal for a Dexter 5,100 lbs axle is item # RG06-070.
As far as the bearing buddy size goes, I can not tell you which one you need off of the axle tag information. I am going to need you to measure the hub bore on one of your trailer's hubs using a digital caliper like item # PTW80157. You'll need to measure down to a thousandth of an inch or 3 numbers past the decimal point.
Once you get this information go ahead and throw it into the comment box below and I'll be happy to find you the correct bearing buddy.
